w-iLab.t Office

The w-iLab.t Office consists of a wireless Wi-Fi (IEEE 802.11a/b/g) and sensor network (IEEE 802.15.4) testbed infrastructure, deployed across three 90 m x 18 m floors of the IBBT office building in Ghent, Belgium. At about 200 spots throughout the office spaces, meeting rooms and corridors, wireless hardware is mounted to the ceiling.  The lay-out of a single floor of the office testbed is displayed below (each dot represents a hardware spot, the color refers to a “testbed zone”).

At each of these spots, following fully configurable hardware is available:

  • 1 embedded PC with 2 Wi-Fi a/b/g interfaces
  • 1 sensor node (TelosB) with temperature, humidity and light sensors and a IEEE 802.15.4 radio interface
  • A custom-designed “environment emulator” board, enabling unique features of the testbed including the triggering of repeatable digital or analog I/O events at the sensor nodes, real-time monitoring of the power consumption, and battery capacity emulation.


Experimenters may use the hardware at all spots or at a subset of these spots, each time enabling either Wi-Fi interfaces, the sensor node, or both devices, to carry out their experiments.
